Turn Text into Natural Voice-overs

An AI voice generator is AI software that uses artificial intelligence to convert text to speech, training deep learning models on human speech. Paste a script or PDF to video, choose a voice, and create an AI voiceover that matches the tone, pacing, and intonation you set. No microphone, studio, or editing experience needed.

Yes. Use our AI voice tools to create lifelike narration with control over pitch, pace, and emotion. Creators use them for YouTube, audiobooks, and advert reads. Anton Voroniuk's case study shows 1,000,000+ students reached using AI voices in his courses.

Paste your script, choose a voice from 300+ options in 175+ languages, and preview the read. Adjust pacing, emotion, and pauses to match your message. Hit generate and download as a high-quality MP3, or pair the voice with an AI spokesperson and captions.

Yes. AI voiceovers on paid plans come with full commercial-use rights for YouTube videos, paid ads, courses, PPT to video, audiobooks, and client work. The free plan is best for testing and personal projects. Check your plan details before monetising.

Yes, you can try the AI voice generator on the free plan with no credit card required. Free users get a monthly voice quota plus a watermark on video exports. Upgrade for higher quotas, premium voices, voice cloning and commercial rights.

Voice cloning trains a bespoke model on a short audio sample, usually about a minute of clean speech. Once cloned, your voice generates new lines from any script whilst keeping your tone and cadence intact. Quite useful for maintaining a signature delivery across thousands of videos.

HeyGen ships with 300+ AI voices covering 175+ languages and dialects, including English, Spanish, Mandarin, Hindi, Arabic, Portuguese, French, German, Japanese, and Korean. Every language carries multiple text to speech voices and a variety of accents so you can match a regional audience precisely.

Free-plan generations have a character cap per clip and a monthly minute quota. Paid plans raise both ceilings, with Enterprise plans supporting long-form audiobook and course workloads. There is no practical limit on total project length on paid tiers.
